`get_blocks_by_type` does not correctly handle pages without relationships (e.g. blank pages) (Python)
If you call TDocument.get_blocks_by_type on a page with no relationships it will instead return as if you called it for the whole document.
E.g. Calling TDocument.tables on a blank page will return all tables in the document.
I believe this is unwanted and unintended behaviour.
This is due to the condition if page and page.relationships:.
In the case of no relationships for the page, the condition evaluates to False.
So instead the blocks returned are for the whole document.
TDocument.relationships_recursive is used to get the list of blocks on the page, which should handle when the page block has no relationships.
Therefore I think this condition can just be if page:?
